There was an error getting the profile for chalkers. (OK)

Why isn't my code working? It should return the username/points/ etc, but I'm getting the following error message: There was an error getting the profile for chalkers. (OK)

//Problem: simple way to view badge count/js points
//Solution: Use Node.js to connect to Treehouse's API to get profile information to print out
var http = require("http");
var username = "chalkers";
//Print out message
function printMessage(username, badgeCount, points){
  var message = username + " has " + badgeCount + " total badge(s) and " + points + " points in Javascript";
  console.log(message)
}
//Print out error messages
function printError(error){
console.error(error.message);
}
//Connect to the API URL (http://teamtreehouse.com/username.json)
  //use http.get
var request = http.get('http://teamtreehouse.com/' +username+ '.json', function(response){
//console.dir(response);
//console.log(response.statusCode);
var body = "";
  //Read data
  response.on('data', function(chunk){
   body += chunk;
  });
  response.on('end', function(){
    if(response.StatusCode===200){
    try{
    var profile = JSON.parse(body);
    printMessage(username, profile.badges.length, profile.points.Javascript)
    } catch(error){
      //Parse Error
      printError(error);
    }
    }
    else{
    //Status Code Error
      printError({message: "There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"});
    }
  });
//parse data
//print data

});

//Connection Error
request.on("error", printError);

The line:

if(response.StatusCode===200){

should be:

if(response.statusCode===200){

You have status capitalized.

Also, on line:

printMessage(username, profile.badges.length, profile.points.Javascript)

should be:

printMessage(username, profile.badges.length, profile.points.JavaScript)

You need to capitalize the 's' in 'JavaScript'.

That should do it. :)

Sean you beat me to this answer by 1 minute! On the other hand, you saved me the time from having to type out the correction! ;-)
